Abstract
The present disclosure provides a novel promoter variant in which some nucleotides are inserted, deleted, or substituted in a twin arginine translocase A (tatA) gene promoter of. According to the present disclosure, the novel promoter variant can constitutively high-express a target protein, particularly an enzyme, in. Therefore, by using a recombinant strain transformed with an expression vector including the novel promoter variant according to the present disclosure, it is possible to economically mass-produce a target protein, particularly an enzyme. For example, by using a recombinant strain transformed with an expression vector including the novel promoter variant according to the present disclosure, it is possible to economically mass-produce allulose epimerase or economically mass-produce allulose from fructose.
